Ceratostigma willmottianum hardy plumbago

Hardy plumbago is a superb substitution for its tender relative common in the Mediterranean.

This one has even deeper blue flowers with 5 petals, mid-green, bristly, obovate, deciduous leaves with purple margins and purple stems. The plants itself is very dense and in full sun bears profusion of flowers.

Grow hardy plumbago in a sheltered position with plenty of sunlight. It is soil tolerant but does best in light, semi-fertile, well drained soil. It is often used in larger rockeries. If it gets damaged after a severe winter just remove dead branches or cut back the plant 10*20 cm above ground level. It will pick up again. Hardy to about -20° or to -24°C with sufficient protection against freezing of basal branches.
